Note:

13/10/2018: The project has migrated from alexa-avs-sample-app to the Alexa AVS SDK. So pre-existing issues have been closed. Have added indicators and audio prompts for Alexa.

The Google Assistant Component used in this project is the GassistPi project. So for 'Preliminary Setups for the customizations and respective How-Tos' check this out

For Google Assistant

1. Download credentials--->.json file (refer to this doc for creating credentials https://developers.google.com/assistant/sdk/develop/python/config-dev-project-and-account)

2. Place the .json file in/home/pi directory

3. DO NOT RENAME THE JSON FILE

For Amazon Alexa

Setup Amazon Alexa, Google Assistant or Both

---

1. Clone the git using:

git clone https://github.com/shivasiddharth/Assistants-Pi  

2. Make the installers executable using:

sudo chmod +x /home/pi/Assistants-Pi/scripts/prep-system.sh    
sudo chmod +x /home/pi/Assistants-Pi/scripts/audio-test.sh   
sudo chmod +x /home/pi/Assistants-Pi/scripts/installer.sh  

3. Prepare the system for installing assistants by updating, upgrading and setting up audio using:

sudo /home/pi/Assistants-Pi/scripts/prep-system.sh

4. Restart the Pi using:

sudo reboot

5. Make sure that contents of asoundrc match the contents of asound.conf
   Open a terminal and type:

sudo nano /etc/asound.conf

Open a second terminal and type:

sudo nano ~/.asoundrc

If the contents of .asoundrc are not same as asound.conf, copy the contents from asound.conf to .asoundrc, save using ctrl+x and y

6. Test the audio setup using:

sudo /home/pi/Assistants-Pi/scripts/audio-test.sh  

7. Restart the Pi using:

sudo reboot

8. Install the assistant/assistants using the following. This is an interactive script, so just follow the onscreen instructions:

sudo /home/pi/Assistants-Pi/scripts/installer.sh  

9. After verification of the assistants, to make them auto start on boot:
   Pi 3 and Pi2 users, open the gassistpi-ok-google.service in the /home/pi/Assistants-Pi/systemd folder and add your project-id and model-id in the indicated points.

Pi Zero users, open the gassistpi-push-button.service in the /home/pi/Assistants-Pi/systemd folder and add your project-id and model-id in the indicated points.

After that, open a terminal and run the following commands:

sudo chmod +x /home/pi/Assistants-Pi/scripts/service-installer.sh
sudo /home/pi/Assistants-Pi/scripts/service-installer.sh  

#If using Pi 2B or Pi 3B
For Alexa:

sudo systemctl enable alexa.service  

For Google Assistant:

sudo systemctl enable gassistpi-ok-google.service  

#If using Pi zero
For Alexa:

sudo systemctl enable alexa.service  

For Google Assistant:

sudo systemctl enable gassistpi-push-button.service

10. Authorize Alexa before restarting

sudo /home/pi/Assistants-Pi/Alexa/startsample.sh  

Manually Start The Google Assistant

At any point of time, if you wish to manually start the assistant:

Ok-Google Hotword/Pi3/Pi2/Armv7 users
Open a terminal and execute the following:

/home/pi/env/bin/python -u /home/pi/GassistPi/src/main.py --device_model_id 'replace this with the model id'

Pushbutton/Pi Zero/Pi B+ and other users
Open a terminal and execute the following:

/home/pi/env/bin/python -u /home/pi/GassistPi/src/pushbutton.py --project-id 'replace this with your project id'  --device-model-id 'replace this with the model id'
